Hey, great post.

I tried to set up multisig account (https://hiveblocks.com/tx/180a74d1454d3ceb9388b6d484737ddb9660b20f) and I have set weight_threshold to 100 and 2 active auths (each 50). But when I try to send a signed transaction, I get a Missing Active Authority error.

Update: It seems error was with dHive, transaction was succesful with Hive-js.
